Chinese Professional TU-3A01 thermal wax actuator for electric switch valve Export to Swiss Detail:
1. Operation Principle
The Thermostatic Wax that has been sealed in shell body induces expansion by a given temperature, and inner rubber seal part drives its handspike to move under expansion pressure to realize a transition from thermal energy into mechanical energy. The Thermostatic Wax brings an upward movement to its handspike, and automatic control of various function are realized by use of upward movement of handspike. The return of handspike is accomplished by negative load in a given returned temperature.
2. Characteristic
(1)Small body size, occupied limited space, and its size and structure may be designed in according to the location where needs to work.
(2)Temperature control is reliable and nicety
(3)No shaking and tranquilization in working condition.
(4)The element doesn’t need special maintenance.
(5)Working life is long.
3.Main Technical Parameters
(1)Handspike’s height may be confirmed by drawing and technical parameters
(2)Handspike movement is relatives to the temperature range of the element, and the effective distance range is from 1.5mm to 20 mm.
(3)Temperature control range of thermal wax actuator is between –20 ~ 230℃.
(4)Lag phenomenon is generally 1 ~ 2℃. Friction of each component part and lag of the component part temperature cause a lag phenomenon. Because there is a difference between up and down curve of traveling distance.
(5)Loading force of thermal wax actuator is difference, it depends on its’ shell size.

Assured Automation- We Make Automation Easy
In this video we will be converting an E Series Fail Closed pneumatic actuator to Fail Open.
First remove the indicator cap from the top of the actuator
Please note that the slot in the shaft is perpendicular to the actuator housing. Next remove spring end caps
To remove the internal pistons, place a wrench on the actuator stem and rotate counterclockwise until the pistons can be pulled out. It is very important to Note the orientation of the pistons as they come out of the actuators, since you will rotate them 180°
Rotate the pistons 180 degrees, Push them into the actuator to engage with the pinion
Rotate the shaft counterclockwise until the pistons are pulled fully into the actuator housing. Note the slot on the shaft should now be parallel to the actuator housing
Reattach and tighten the spring end caps
Attach indicator cap
The actuator should rotate clockwise when air is applied. It should spring closed counter clockwise when air is removed.

Our Goal is to make the selection, estimating and delivery of high quality automated valves and flow components as quick and easy as possible.
During a client install of several concrete duct banks under existing highways an installation error caused damage to the PVC power cable conduit. The damage consisted of large perforations in the conduit and partial engulfment of the PVC conduit with wet concrete. During attempts by other contractors to remedy the situation, the PVC conduit was destroyed in many areas. Thermal conductivity specifications required tight tolerances for the repair.
EA Services, Inc./ Pipelining USA designed and fabricated a proprietary, rotational grouting robotic apparatus to build new smooth pipe walls where the existing ones had been destroyed.
EA Services Inc. robotically lined the entire conduit with StructrLine FS to provide structural support, to compensate for thermal tolerances, and to decrease friction for the installation of the 7″ solid copper cable.
Due to EA Services, Inc. / Pipelining USA’s rapid innovation and production of the rotational grouting apparatus, as well as our StructrLine FS material, the damaged sections were successfully rebuilt and all perforations were closed.
